. Referring more particularly to the drawings, my construction isadapted not only forioriginal installatiosin the building of newwindows, but also installations in existing windows, and is a windowembodying adapted to be fitted intoethev conventional frame 2i! as anauxiliary to the conventional window 2i. I provide channel members-25having a pair of inwardly extending Vflanges 26 and 2.1,: and anadditional ange 28 at right angles thereto. Flanges 26 and 2l Aprovide achannelZQ in which is formed a U-shaped mem-ber 3B which deiines, withthe iianges 25 and 2l, grooves 3! and 32 therein. The flange 28 lisprovided at spaced intervals with screw holes 33 for installationpurposes. y f

`The channel member is adapted for installation in both the upper andlower sash being only necessary to reverse 4it from one position to theother.` Referring to Fig. 2, the channel member 25 is installed withthe-.flange 28. against the window stop 35 for the upper. sash,.while inthe lower, the flange 2B is installed against the window stop. In thismanner the lower sash 35 may be raised inside theuppersash 3l.

It will be appreciated that the channel members 25 must not only beinstalled on .the sides of the window for the upper and .lower sash, butat the to'p thereof, as shown at 33. At .the bottom of. the window I.further install a member 6.0, due to the factthat in anormal window thelowersash is of greater length than the upper sash, the member 4E) willcompensatefor the difference in length andmake it possible to use anupper and lower-sash of identical size. The member lidisfastened to theinner sill. and window stops by lmeans of screws, lll. At its lowerendit is provided with a channel i3 which, after installation, iscaulked with a suitable compound. .At its upper edge the, member 40 isprovided withfa U-shaped member 45 slightly narrower in width thanthemember itself..

The. window frame is made of prefabricated stock 50 which is provided.at its inner side with aslot. 5l adapted to4 receive a pane of glass 52.

i The slot 5i leads to a chamber 53 in which may be mounted a sealinggasket 54. The member 59 is provided with two flanges 5t and '5l deningthe channel. It will be seen that when the' window is fitted theilanges56 and 51 engage the channels 3l and 3 2 of the-channel member 35, whilethe U-shaped member 3B is engaged in the channel 58 to insure a closefit.

In making the sash frame 60, the stock 50 is ont to the appropriatelength and the holes 6I bored at the desired place. The four sides ofthe window are then assembled by meansV of the corner piece-52 whichh-as inner and outer portions 53 and 64 matching the sides 65 of themember 5B'. The corner portionv62 is provided with an elbow member 66which has a channel 61 and the elbow portion is .adapted to fit withinchamber '53 behind slot 5I in the memberll;` as indicated in Fig. 6. Theelbow member 6571s also provided with tapped holes 68 -to fasten thecorners together, As all four sides of the window are constructed of thesame material, it is a simple matter to cut the stock to the desiredsize and quickly t it together by means of the corner members 62.

In the past, most windows of this type have been welded or otherwisepermanently fastened together, and when a pane of glass is broken, it isnecessary to return them to the factory. With my improved construction,the glass may be readily replaced by removing one end and its adjoiningcorner portions.

In installing my window the channel strips 25 are fastened to the frameof the window against the stop 33, the channel strips for the upperwindow having the'flange 28 against the window stops, while the channelstrips for the lower window are reversed. Caulking compound is insertedin the channel 30 to completely seal the channel strips to the frame.The member 40 is then put in place. rIhe lower window 3E is put intoplace first and .the upper window 3l may then be slid into place. Inorder to hold the upper window in closed position, a hinged latch 15,having an extending member 16 abutting the under side of the window, maybe provided on either side. In order to seal the windows when closed,the strip 'll is fastened to the top of the lower window, and a similarstrip '|8 is fastened to the bottom of the upper window, as most clearlyshown in Fig. 9. Since it may be desired toopen the lower window forventilation, latches 80 may be provided at convenient places. The latch80 consists of two members 8| and 82, the latter being a handle memberand is pivoted by the screw 83.

As the window is raised, the member 8| will tend to fall outwardly andthe window will be caught by the latch surface 84. It will beappreciated that it may be readily released by moving the handle member82 toward the glass.

When it is desired to remove the windows they are removed in the sameway by opening the hinged member and allowing the upper sash to slidedownwardly and then by removing the lower sash. Screens 90, as shown inFig. 13, are provided, having ends 9| adapted to fit within the channel29. Since an air seal is unnecessary with screens, the end 9| may berectangular. Obviously, any type of screen may be used, but one mostsuitable is shown in Figs. 13 and 14, which may be cut of standard stockand provided with a channel 92 and a wedge member 93 to hold the screenin place. The stock may be joined ,by the corner member 94 to hold thescreen together.

Where it is desirable or necessary to have two or more lights in awindow, a T-member |00 is provided. Like the corner member 62, the T-member has two portions |0| and |02 matching the stock 50, and arms |03,|il4 and |05 adapted to engage the stock to fasten it together,

While the material used does not formv an essential feature of myinvention, quite obviously metal or other materials may be molded orpressed as most suitable, since the channel strips may be pressed out ofsheetl material, while the stock 50 can most readily be pressed andwelded together. Lighter metals may readily be used since there are nostresses or strains involved. The lower sash 3B may also be providedwith a handle member 39 to facilitate its raising and lowering. v

I claim:

1. A window sash formed of channel. stock members which meet at thecorners of said sash leaving a corner space therebetween, corner memberswhich join said channel members and occupy said corner space, and meansfor fastening said corner members to said channel members, said channelmembers being substantially H- shaped in cross section, and havinginwardly extending ilanges formed on the inner edges of their sidewalls,thereby dening an inner chamber underneath said flanges, a glassreceiving slot between said anges, and an outer guiding channel, saidcorner members comprising L-shaped elements which are U-shaped in crosssection and having side plates aixed thereto and extending in partbeyond said L-shaped elements, said L-shaped elements being adapted toenter the inner chambers of adjoining channel members and to complementsaid glass receiving slot, said side plates being adapted to complementthe side walls of said adjoining channel members and to occupy thecorner space therebetween, the Y channels formed between the outwardlyextending parts of said plates and said L-shaped elements continuing andcomplementing the outer guiding channels of said channel members.
